Lub Hom Phiaj: Xa ib qho kev txiav txim siab rov ua dua tshiab rau kev xaiv Servo lossis stepper motors hauv desktop CNC ua nyob hauv qab 1 m³ ua haujlwm ntim.
Txoj Kev: Kev ntsuas kev ntsuas pom tseeb emulated ib tug 3 {{}}}}} {{5} {{7} ntsia hlau). Plaub caug-yim sib tw khiav piv Nema 23 Steppers (2.8 A, 1.8 degree) thiab 200 w txhuam hniav (3000 rpm, 17-ntsis encoder). Dynamic txhav txhav, muab txoj kev ua yuam kev, lub zog hluav taws xob tiag tiag, thiab 8-teev thermal sawv tau logged ntawm 100 mm / s kev hloov pauv.
Cov txiaj ntsig: tsawg dua li lossis sib npaug zos rau 200 hli / s, steppers xa ± 0.05 hli rinnability nrog 25% qis dua tus nqi. Saum toj 400 mm / s, servos tswj ± 0.01 mm thaum txiav hluav taws xob 18% thiab txwv tiv tauj txog 8℃rau steppers.
Xaus: Steppers nplua qis - nrawm, pob nyiaj- ua ntej tsim; Servoos ua kev lag luam saum toj no 400 mm / s los yog thaum thermal stability thiab micron- qib yog qhov yog.
1 Taw qhia
Xaiv lub cev muaj zog tsis zoo thiab koj lub desktop cnc yog cov khoom siv ntawm txhuas lossis hlawv nyiaj txiag ntawm cov khoom siv hluav taws xob overkill. Cov lus qhia no taug kev dhau los ntawm kev ntsuas ntsuas, thiab cov qauv siv ntawm cov kab kos, thiab cov qauv them nyiaj rau koj tus kheej lub rooj ntev thiab ntsaws tus lej ncaj qha rau hauv ib daim ntawv.

2.3 Ntsuas
- Txoj hauj lwm: 0.1 μm iav - cov nplai Ecoder, ywj pheej ntawm lub cev muaj zog tawm tswv yim.
- Lub Hwj Chim: Yokogawa WT310, 0.1 D Recolution.
- Thermal: k {- Hom Thermocouple rau cov tsiaj muaj zog.
- Kev tswj: Linuxcnc 2.9, 1 KHUZ servo xov rau ob qho Systems.
2.4 Cov txheej txheem (rov ua dua)
Kauj Ruam 1: Jog txhua AXIS 100 hli ntawm 100 hli / S → Log Txuas qab yuam kev.
Kauj Ruam 2: Rov ua dua ntawm 200, 400, 600 hli / s.
Kauj ruam 3: Clamp A 5 kg dummy spindle, khiav ib qho 30 - Min g-code qauv ntawm 50% dej num.
Kauj Ruam 4: Sau cov ntaub ntawv ntsuas kub txhua 60 s.
Kauj Ruam 5: Sib pauv lub cev muaj zog ntau yam, ua kom mechanics zoo ib yam, Rerun.
3 tau txais & tsom xam
3.1 Qhov chaw ua hauj lwm raug
Daim duab 1 daim duab lub ntsiab lus tsis raug raws li kev ua yuam kev hla kev traverse. Steppers stay under 0.05 mm up to 200 mm/s, then climb steeply to 0.18 mm at 600 mm/s. Service nyob ruaj ntseg tiaj tus ntawm 0.01 hli thoob plaws ntau yam.
3.2 FAIS & KUB KUB
Rooj 1 lub ntsiab lus nruab nrab lub zog tiag tiag thiab ΔT tom qab 30 min.

| 600 | 65 | 53 | 22 | 8 |
3.3 torque ntawm nrawm
Daim duab 2 overlays torque-ceev curves. Tus topper torque dentops 60% los ntawm 0 RPM txog 1200 RPM. Servo Torque tuav tau tsis pub dhau 5% txog 3000 RPM.
3.4 Tus Qauv Nqi
- Cov npe teev cov npe nqi rau ib axis (USD, 2025 Q2 quotes):
- Stepper Khoom Siv (Tsav + Tsav Tsheb + PSU Qhia Tawm): $ 42
- Servo Khoom (TSAV + tsav + encoder cable): $ 115
Txhaum -} Txawm tshwm sim thaum lub voj voog - lub sij hawm txuag ntawm servos outweigh tus nqi $ 73 hwm. Rau ib tug 10 {- teev / vas thiv / lub lim tiam tshuab txiav ntawm 600 hli (s, tawg ntawm 14 lub lis piam (Daim Duab 3).
4 kev sib tham
4.1 Vim li cas Steppers poob qhov tseeb ntawm kev nrawm
Yuav tsum torque ripple thiab rov qab - emf txwv winding lub sijhawm nce tam sim no. Tsis muaj lus qhia txhais tau tias tsis tau ua tiav cov kauj ruam mus rau txoj kev tsis raug cai.
4.2 Servo Trade -} Offs
Lub encoder ntxiv 32 mm rau lub cev muaj zog ntev tab sis tshem tawm cov kev pheej hmoo stall. Pid tuning coj 15 min ib axis; Lub neej ntawd tau txais tau ruaj khov rau peb cov kev thauj khoom (j_load / j_rotrotor ≈ 5).
4.3 Qhov Txwv
- Kev ntsuam xyuas siv 24 Val npav; Ntau dua voltage (48 V) yuav txuas ntxiv cov neeg ruam ruam ceev ceev.
- Thermal kev sim uas tau siv tsis muaj qhov thaiv; Lub zog cua sov tuaj yeem nqaim tau 14℃sib txawv.
4.4 Cov tswv yim nqa khoom
Yog tias koj txoj haujlwm nyob qis dua ntawm 200 hli / S thiab Micron ua tiav tsis tseem ceeb, steppers txuag nyiaj thiab xaim. Push dhau 400 mm / s, vegrave meters, lossis xav tau 24 {{{{{} teev rau lawv tus kheej rau kev ntseeg tau thiab muaj txiaj ntsig zoo.
5 lub ntsiab lus
Steppers yeej ntawm kev yooj yim thiab upfront tus nqi rau lub teeb - lub luag dej desktop cnc. Servoc dominate thaum ceev, raug, lossis thermal kawg teeb meem. Siv qhov tawg {{3-} daim duab (daim duab 3) los txiav txim siab {} ces Rerun 30-}- Tom qab ntawd koj tus kheej lub rooj ntev zaum kom paub meej ua ntej koj ua txhaum.
